In binutils 2.40 and earlier versions, only a warning will be reported when a relocation immediate value is out of bounds. As a result, the value of the macro HAVE_AS_COND_BRANCH_RELAXATION will also be defined as 1 when the assembler does not support conditional branch relaxation. Therefore, add the compilation option "--fatal-warnings" to avoid this problem.gcc/ChangeLog: * configure: Regenerate. * configure.ac: Add parameter "--fatal-warnings" to assemble when checking whether the assemble support conditional branch relaxation. --- gcc/configure | 2 +- gcc/configure.ac | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/gcc/configure b/gcc/configure index 41b978b0380..f1d434fede0 100755 --- a/gcc/configure +++ b/gcc/configure @@ -31136,7 +31136,7 @@ else nop .endr beq $a0,$a1,a' > conftest.s - if { ac_try='$gcc_cv_as $gcc_cv_as_flags -o conftest.o conftest.s >&5' + if { ac_try='$gcc_cv_as $gcc_cv_as_flags --fatal-warnings -o conftest.o conftest.s >&5' { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$ac_try\""; } >&5 (eval $ac_try) 2>&5 ac_status=$? diff --git a/gcc/configure.ac b/gcc/configure.ac index 72012d61e67..9ebc578e4cc 100644 --- a/gcc/configure.ac +++ b/gcc/configure.ac @@ -5486,7 +5486,7 @@ x: [Define if your assembler supports -mrelax option.])]) gcc_GAS_CHECK_FEATURE([conditional branch relaxation support], gcc_cv_as_loongarch_cond_branch_relax, - [], + [--fatal-warnings], [a: .rept 32769 nop
